However, they are constraint in one way or other. This paper therefore revisited the rainfall simulator as potential tool for hydrological research. The research disclosed that there are three different types of rainfall simulators; drop former simulator, pressure nozzle simulator and hybrid simulator. It can further be classified as indoor model and outdoor. The research also showed that precipitation is the driving force in hydrological studies. Consequently, in the design of rainfall simulator, the following should be taken into consideration: nozzle spacing, pump size, nozzle size, nozzle type, nozzle spacing, plot size and pressure. Meanwhile, intensity, distribution uniformity, kinetic energy, rainfall drop size and rainfall terminal velocity should be noted in its evaluation. Factoring-in the aforementioned design considerations, data collection is made easy without necessarily waiting for the natural rainfall. Since the rainfall can be controlled, the erratic and unpredictable changeability of natural rainfall is eliminated. Emanating from the findings, pressurized rainfall simulator produces rainfall characteristics similar to natural rainfall, which is therefore recommended for laboratory use if natural rainfall-like characteristics is the main target.

This book was released on 2020 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrologic and Hydraulic practices depend on the characterization of extreme precipitation that is rare in nature. Despite the advancement in sensing technology, the observation record of extreme rainfall with good spatio-temporal resolution has not reached a sufficient length. Furthermore, rainfall observation may never be sufficient in a non-stationary climate. Towards solutions to these issues, rainfall simulation was explored in this study (1) to investigate hydrologic responses to storm characteristics and (2) to facilitate rainfall frequency analysis. To that end, this study initially employed storm transposition plus hydrologic simulation for generating possible rainfall-runoff scenarios which further reveal relationships between storm characteristics and hydrologic responses from an urban watershed, Brays Bayou in Houston. Consequently, this study generated meaningful findings highlighting the role of Brays Bayou's flat terrain in affecting flood peaks. Meanwhile, limitations in storm transposition were exposed and led to the development of a Dynamic Moving Storm (DMS) generator in the second part of this study. The DMS generator consists of three fundamental components, storm movement, spatial and temporal variabilities of rainfall intensity. By parameterizing each component, a vast variety of rainfall scenarios could be generated, simulated, and then analyzed again using Brays Bayou as the test bed. Hydrologic responses were revealed as results of not only individual parameters but also parameter interaction. The findings confirmed and augmented those based on the storm transposition approach. In accord with previous studies, storms moving downstream at the same velocity as stream flow were found to cause the resonance effect on flood peaks. Brays Bayou's flat terrain was the key in explaining the patterns in various flood peaks and storm parameters. As the last part of this study, a stochastic storm generator was developed featuring optimal estimation for spatio-temporal modeling of rain fields and a non-parametric approach for generating model parameters. A case study in Dallas-Fort Worth Metroplex was conducted to generate possible realizations of 100 most rainy days at high spatio-temporal resolution. As the first step towards applying a long-term stochastic rainfall simulation, this approach was proved to offer many attractive traits, as statistical properties of observed rainfall were well preserved in simulations requiring only a small number of parameters. Collectively, this study offers innovative pathways for better utilizing rainfall information in flood modeling and rainfall frequency analysis with reduced uncertainties from the limited records of extreme storm events that make them feasible alternatives to traditional approaches.

Book excerpt: Rain simulation systems have been designed for field and greenhouse studies which have the capability of reproducing the physical and chemical characteristics of natural rainfall. The systems permit the simulation of variations in rainfall and droplet size similar to that of natural precipitation. The systems are completely automatic and programmable, allowing unattended operation for periods of up to one week, and have been used to expose not only vegetation but also soils and engineering materials, making them versatile tools for studies involving simulated precipitation.
